Kite is quadrilateral with consecutive sides that are congruent
*Indicated pairs of consecutive sides in the following orientation of kite







Properties

Diagonal Properties

1. One diagonal bisects the other
*Indicated diagonal in the following orientation of kite

2. Diagonals are perpendicular to each other

This is the most important property of a kite for the following reasons:
- Knowing that these angles (formed by intersection of the diagonals ) are 90 degrees, congruence of consecutive triangles (Triangle KIA & Triangle TIA, Triangle EKA & Triangle ETA) can be proved using CPCTC
- Knowing that these angles are 90 degrees can partially help find side measures in relation to base angle measurements






Angle Properties
1. One pair of opposite angles is congruent
*Applies to indicated pairs of opposite sides in the following orientation of the kite

Example Proof
Prove: Angle IKE is congruent to Angle ITE

2. Consecutive triangles formed by the diagonals are congruent
*Indicated pairs of consecutive triangles in the following orientation of kite
